Abstract

The availability of images in different applications is augmented owing to the technological advancement which cannot impact on several image operations, on availability of sophisticated software tools that manipulate the image management. Compression is a method for storing easier for large amount of data by dropping the amount of bits to pile up and pass on digital media. Therefore, Image compression has proved to be a valuable technique as one solution. In this paper, a quick lossless compression method like Huffman and LZW method is implemented which consists of two stages. In the initial phase, a Huffman coding is used to compress the image. In the later stage all Huffman code words are mergted together and compressed with LZW coding. This procedure is easy in performance and use a lesser amount of memory. Image compression algorithms have been proved and applied to compress and decompress the image by MATLAB environment.
